They look amazing compared to PS3 games, and I feel like they play a lot better.
No you will not be able to play the games either way. Systems changes on the PS4 allow them more design capability for games and many titles will be released in a downgraded PS3 version. You still will have to have a PS4 to play PS4 games and a PS3 to play PS3 games.
No, the PS4 does not have backward capability and cannot activate (play) PS3 or PS2 games.
In short, no. Sony haven't released any information regarding a PS4 yet, so we can only assume that you cannot. It is highly likely you will be able to play PS3 games on it, that is - if it really comes out.
No, the PS4 will only run the games made for the system. But there is a application on PS4 called PlayStation Now which will allow you to play PS3/PS2 games for a price.
No. Steam games run on PC/mac and not on Sony PS4 (or nintendo or xbox) at all.
The Ps4 of course because it has much better graphics and the Wii U is a kid friendly and the ps4 also if you like sport games you will have to get a ps4 because the wii u doesn't have sports games if you want to talk to someone you can't do that on the Wii u only on the ps4.So the choice is a ps4
No. It is not possible for a PS3 version of a game that is also offered as a PS4 game title to play against each other. They can not play because the games are different software and whether they are both on the Playstation Network does not matter because the games are not compatible
No the games and PS4 system have not yet been released and there is nowhere to play them unless you are part of the EA family of developers with an advanced release PS4 for the game developers
Yes, you must buy a PSPlus membership to play online games on the PS4.
You can buy a PS4 at any good games retailer both in stores and online
It wont be released for ps4, but if ps4 can run ps3 games, than your answer is yes.
No, there is no plan for PlayStation to stop making PS3 games. The company recently released the PS4 console. PS3 games do not work in the PS4.
